A quick modification of Mr_Nick666's forwarder channel for use on the Wii U (vWii).
I simply used ShowMiiWads to replace the 00000001.app file inside the WAD with the vWii compatible version and changed the title ID from SCUM to ECUM so that the vWii loads ScummVM in the proper 4:3 Aspect Ratio. This way your games can be played the way they were designed (All the games I own were designed for 4:3 at least).
